TYPEWRIIIN'G 'MACHINE.

Application filed m 14, 1925. Serial No. 43,492.

This invention relates to stencil-card holding-and-typing' devices fortypewriting machines, in which a card-holding frame is arranged toreciprocate tangential y to a revoluble platen.

This device is particularly arranged for use in connection withstencil-cards for 'addressing machines which comprise acomparatively-heavy paper or cardboard frame having an opening, acrosswhich is stretched a stencil-sheet. It is sometimes desirable-to typesome information on the paper-frame, and then withdraw or silence thetyping ribbon to write the full name and address on the stencil-sheetdirectly with the "bare types.

There is disclosed improved means for automatically controlling theribbon mechanism, so that it may be vibrated in front of 2 the types atcertain times, but silenced while the types are striking thestencil-blank.

According to certain features of this invention, the stencil-card isplaced in a cardholding frame, tangentiall 1 disposed in front of theplaten, and means of a handle the card-holding frame, is lowered to apoint to receive-the first lineof tvping at aha upper edge of thepaper-frame. ovel me anism is effective at this position of the card tovibrate the ribbon, and conseqently a lineis typed upon the frame of thecard.

QBy means of the usual line-spacing mechanism, the card maybeline-spaced several lines during the typing of other lines upon thecard-frame,with the aid of the ribbon.

The card-controlling handle is then swung, and by means of a novelstop-device the handle is arrested in a position corresponding to thefirst line of typing upon the 40 stencil-sheet. During the swinging ofthe handle to raise the card, the ribbon-vibratmg mechanism is silenced,and automatically the machine is converted into a stencil-cutter. Bymeans of the line-spacing mechanism, the card may again be linespaced inthe regular way as fresh lines of typing are cut into the stencil-sheet.

' In order to permit the line-spacing of the card while cutting into thestencil sheet, the

stop-device, designed to arrest the handle in a position correspondingto the first'line of typing on the stencil-sheet; is automaticallywithdrawn as the handle is released,

thereby making it possible to move the handle further to the rear as thecardis line-spaced.

From the foregoing, it will be seen that the card is handled with aminimum eflort on the part of the o erative, who need not shift theribbon-mec anism, which is automatically thrown into operation whenneeded and silenced when not required.

Owingto the comparatively long cards used in this type of machine, andto the desirability of presenting the card to the platen in a fiatcondition, it is contrived to lower the card in an inclined pathtangential to the platen. This clears the type-bar segment, which isplaced below the platen and in line therewith. The printing point is, inthis invention, considerably below the plane of the platen-axis, asusual heretofore. To vibrate the ribbon in front of the inclined card,in a path parallel thereto, novel mechanism is provided.

In order to eliminate the blurring of the typing, which would occur ifthe type-barheads were caused to bear upon the work sheet, and also toimprove the return s eed of the type-bars, there is usually provided ananvil against which the type-bars strike previously to striking thework-sheet, the printing upon the sheet being caused by the resiliencyof the type-bars. In order that this feature may be maintained bothwhile typing upon the stencil-frame and upon the stencil-sheet, novelmechanism is provided whereby the anvil may be adjusted slightly towardsand away from the platen. difference in thickness between the 'cardframeand the stencil-sheet is automatically compensated for by the positionof the cardframe.

When cutting the stencil-sheet, it is desir able to provide a backingfor the card to both protect the types and facilitate the cutting of thestencil-sheet. Novel means are rovided to automatically present thebackmg to the stencil-sheet only, the platen being rotated whileline-spacing the card. In this manner, owing to the positive gearconnec-- tion between the platen and the card-frame, and, due to thestandardization of the cards, the stencil-sheet therein at all timescorresponds to the same portion of'the platen, which is-covered with acelluloid strip fastened to the platen by means of a clampingmember,--so built into the platen as to. pre- The I sent an unobstructedplaten-surface, and thus permit the feeding of the cards up and down asthe platen is rotated. in a path tangential thereto. Indrder tofacilitate the reading of the typed matter upon the stencil-sheet, theremay be provided inking means wrapped around the celluloid strip andfastened to the platen with the celluloid by means of the same holdingdevice.

Other features and advantages will hereinafter appear.

This invention is illustrated as applied to an Underwood standardtypewriting machine and is particularly suited for the handling of ofcards, such as used in some addressing machines. In Figure 25 there isshown a stencil-card consisting of a heavy paper or cardboard framehaving an appendage at the top thereof, upon which it is desired to typeseveral lines 11 for the purpose of identifying, or otherwise relatingto the addresses typed upon a stencilsheet 12, stretched across anopening 13 in the lower part of the card, the typing 14 on thestencil-sheet being, of course, desirable to be typed with the baretype, so as to cut into the sheet, thus providing a passage for the ink.

According to the method of handling the card 10, the same is inserted ina recess in side frames 16, behind plates 17 and is lowered all the waydown against a stop-bar 18, which forms an integral part of the sideframes 16 comprising the cardholdin 'frame. The position of the cardafter being inserted in the card-holding frame is illustrated in Figure1.

The card-holding frame is then lowered to the position shown in Figure4, for the purpose of writing the first line of typing at the top of thecard. In order to quickly and positively lower the card to printingposition, there is provided novel mechanism including a handle 19operatively connected to a sector 20 geared at 21, and engaging with apinion 22. The pinion 22 is fast to a platen-shaft 23, which carries,fast thereto, a platen 24 and a pair of gears 25, l

.in turn meshing with racks 26, forming an wardly, the sector will alsobe swung, and consequently the card will be lowered.

As it one of the mainfeatures of this invention that theribbon-vibrating mechanism shall be automatically controlled bythe-movement of the card in a manner to afford the rising of the ribbonin front of the types at each key-depression, there is providedmechanism which is operatively connected to a universal bar 27. In orderto more fully comprehend the operation of the ribbon-vibratingmechanism, first the action of the ty )e-bars will be described.

Upon depressing each key (not shown), a key-lever 28 is swung on afulcrum-shaft 29 against the action of a. spring 30, and, by inc-ans ofa pin 31 engaging with-a slot in an. intermediate lever 32, the latteris also swung on a pivot The lever 32 is provided at the upper endthereof with a pin 34 engaging a slot in atype-bar 35, whereupon, upondepressing the key, the type-bar is swung on a supportin pin 36. thusstriking the card by means 0 a type 37. In order to letterspace thecarriage after each type-impression, there is provided mechanismcomprising a'pair of dogs 38, engaging with an escapement-wheel 39,which, in turn, engages, by means of a pinion 40 and a rack 41, with thecarriage. The dogs 38 are controlled by the universal bar 27 which isbent downwardly at 42 and then rea-rwardly at 43, and again upwardly at44, forming a pocket 45 for the card. The universal bar is supported inthe regular manner upon a supporting member 46 sliding in the typebarsegment 47 and upon a rocking arm 48 at the rear of the machine. It willbe understood that upon swinging each type-bar, the universal bar ismoved to the rear, because each type-bar is provided with a heel 5Ostriking .a curvate sector 51, which forms an integral part of saiduniversal bar, which is ope5rg-tively connected to the escapement-dogsat Normally, in a typewriting machine, the

universal bar is operated back and forth at each key-depression. In thepresent matit) chine, a ribbon 53 is held silent in its normal positionbelow theprinting point, as shown in Figure 1. However, upon loweringthe card-holding frame and immediately after the stencil-sheet passesthe printing field, the ribbon is operatively connected to a round pin54 fast to a bracket 55, forming a part of the universal bar. Novelmechanism is provided in this invention for the purpose "of connectingthe ribbon-mechanism to the universal bar when the paper-frame of thecard is in the printing field, and for silencing the ribbon while thestencil-sheet is in the printing field. As it is proposed to switch theribbon-mechanism automatically,

mechanism is also provided which, in one ,fgrm 'of this invention,comprises a cross-bar 56 fast to the stop-bar 18 of the card-holdingframe, and a rotatably mounted plate 58 having two teeth 59 and60'engaging with connected to said plate 58 at 62, is drawn up,

thus rocking-an arm 63 to which the link 61 isconnected at 64. The arm63 is fast to a shaft 65"rotatably mounted in a bushing 66 fast toasupporting bracket 67. At. the other side of the bushing 66, the shaftis provided with a head 68 forming an integral part thereof, into whichhead a shoulder-stud 69 is screwed eccentrically with the shaft, andupon which screw a ribbon-controlling arm 70 is rotatably mounted. Saidarm 70 is fast to a'bushing 71, which carries at the other side thereof,also fast thereto, an upwardlyextdnding arm 72, having an open slot73'at the endthereof, designed to engage the pin 54 in the universalbar. According to this arrangement, the arm 70 forms substantially 'anintegral part of the arm 72, so that, when the latter is engaged withthe pin, and the universal bar is moved, then both arms are rocked ontheir supporting stud 69, thereby lifting the ribbon in front of thetypes by means of a link 74 operatively connected to the arm 70 at 7 5.In order that the slot 73 in the arm 7 2 may be in a position to engagethe pin 54 when urged upwardly by the link 61, the arm 70 is providedwith a locating finger ,76 at the end thereof, normally resting on a rib77 of the machine-frame, which is generally indicated by the numeral'78. When the arm 72 is raised, the pin 54, while entering the slot 73,acts as a cam and swings the arms 70 and 72 slightly counterclockwiseand raises the finger 76 a short distance from the rib 77, as shown inFigiire 4.

Owing to the design of the card-holder which is caused to be moved upand down in aninclined'path in front of the platen, it is necessary tovibrate the ribbon in front of the card also in an inclined pathparallel thereto. To this end, there is provided mechanism whichcomprises a guiding member 79 fast to the type-bar segment 47 by meansof screws80, and a ribbon-vibrator 81 provided with fingers 82 to guidethe ribbon. The ribbon-vibrator is operatively connected to the link 74at 83, the lower end of the link being connected to the arm '70 andallied mechanism in the manner hereinbefore disclosed.

Mechanism is provided to positively hold the ribbon in eitherits'efi'ective or ineffective to co-operate with a tooth 87:,on .theplate 58,'and, owing to the resiliencyfofthe arm actuated by a spring88, when the plate 58 is rotated-by the action of the bar 56, it will beheld in place by the force of the roller actuating upon either side ofthe tooth 87. However, such mechanism would "require the spring 88 to becomparatively strong, thereby rendering the operation of the handlehard, or else the mechanism would be unreliable. In order to render thetiming of the ribbon-mechanism more positive, there is provided alocking member 89, rockably mounted on a shaft 90 journaled in thebracket 67. Said locking member is provided with a tooth 91, engagingwith notches 92 by means of a spring 89 in a disk 93 fast to a. shaft94. Referring to' Figure 9, it will be noted that the locking member iscontrolled by a cam-finger 95 fast on the shaft 94 against which fingerthe bar 56 actuates to swing the locking member, thus withdrawing thetooth 91 from engagement with the notches 92 previously to strik ingeither of the teeth 59 or 60, to rotate the plate 58 and to render theribbon effective to vibrate.

Having written one or more lines of typing upon the paper-frame of thecard, the handle 19 is then swung to the rear to move the card upwardlyin a position to receive the first line of typing upon the stencilshect.In order to quickly position the card, and at the same time permit itsbeing linespaced by means of the line-spacing mechanism 96, the handleis rotatably mounted upon a stud 97, fast to one of the side plates 98,and is provided witha pawl 99 pivotally mounted on a stud 100 fast tothe handle so that the rear rim portion of the pawl may engage thesector 20 upon movement of the handle clockwise. Due to the peculiarmanner in which the handle is connected to the sector 20, the same maybe rotated counterclockwise a small amount be fore a tab 101, forming anintegral part of the handle, strikes the sector, thereby driving thesector therewith. In order to bring the tab 101 in contact with thesector, however, the tension of a spring 102 normally tending toseparate the tab from the sector must be overcome, and, in so doing, thepawl 99, which is normally held in the position shown in Figure 4 by thesector bearing upon a heel 103 of the pawl, is permitted to swing to theposition shown in Figure 9. in which position it is held by the actionof a spring 101, thereby striking a tab 105 of a stop-device 106, thetab extending through an opening 107 in one of the plates 98, thusarresting the swing of the handle and of the card. Upon releasing thehandle, the spring 102 is allowed to retract, thereby swinging thehandle rearwardly to separate the tab 101 from the sector, andconsequently forcing the swinging of the pawl 99 to its normal position,thereby clearing the tab 105 of the stop-devicaand consequentlypermitting the line-feedin of the platen by means 01': the line-spacingmechanism. In order to accurately position the stencil-card to receivethe first line of typing upon the stencil-sheet, the stop-device 106 isrockably mounted upon the stud 97 by means of a screw 108, and isscttable upon the plate after being adjusted by means of screws 109through circular slots 110 in the stop-device 106. It will be noted thatthere is provided a similar stop-device 111 having a tab 112 for thepurpose of interposing the sector 20 at 113, as shown in Figure 4,thereby locating the card for its lowermost position. The tab 112protrudes through an opening 114, which is adjustably mounted on thescrew 108 and is settable by means of screws 115 through a circular slot116.

It. will be understood that, upon raising the card-holding frame fromits lowermost position to a position to receive typing upon thetencil-sheet. the bar 56 strikes the tooth 59 of the plate 58, therebydisconnecting the ribbon'vibrator from its operating pin 54: in theuniversal bar, thus permitting the typing of one or more lines upon thestencilsheet with the bare type.

Owing to the positive gearing, connecting the card-holding frame withthe platen, a certain portion of the periphery of the platen correspondswith the opening in the card across which the stencil-sheet stretched.This condition is taken advantage of, in this invention, to provide acelluloid strip 117 for the types fixed upon a portion of the platen 24and wrapped therearound. Novel means are provided for holding the strip,and, if desired, an inking medium associated therewith. The holdingmeans may comprise a longitudinal groove 118 out into the platen, intowhich groove a bent edge 119 of the strip is placed, as shown in Figure10. Then the platen is rotated to expose the other bent edge 120 of thestrip, as shown in Figure 11, whereupon the edge 120 is forced into aroove 122 behind an eccentric bar 121, whlch is subsequently rotated tothe position shown in Figure 12, thereby binding the ed e against theside of the groove 122. Mec anismis provided to rotate the eccentric bar121, which comprises an operating plate 123 fulcrumed in the platen-axle23, and operated therearound by means of a finger-piece 125. The plateis provided with a pin 126, engaging with a slot in an arm 127, fast tothe bar 121 at vthe end thereof.

In order to compensate for the difference in thickness between thecard-frame and the stencil-sheet, there is provided mechanismautomatically controlled by the shaft 94, which is, in turn, controlledby the position of the card. It is well known that the Underwoodtypewriting machine is provided with an anvil against which all thetype-bars strike previously to striking the work-sheet, which is struckbecause of the resiliency of the type-bars. The amount that thetype-bars are caused to bend in order to a strike the sheet is so smallthat if the bars were adjusted by the thick cardboard frame of thecards, then the type-bars would not strike the stencil-sheet. In orderto eliminate this condition, an anvil 128 is provided adjustably mountedon the type-bar segment in a manner to afford its bein built u whentyping upon the card, an decrease when typing upon the stencil-sheet. For the purpose specified, a stop-ring or pad 129 is partly milled off inan, angle with a vertical plane through the axis of the platen, and theanvil 128 is slidably mounted thereon. The anvil is also milled in anangle but opposite to the milled angular face 0 thepad'129,'in such amanner that the outer,

face of the anvil will be substantially parallel to the axis of theplaten. It is obvious that by sliding the anvil upon the pad the outersurface will be moved either forward- 1y1 or rearwardly depending in thedirection t e anvil is swung upon its supporting pad, against which itis held by means of studs 130 fast to the anvil as shown at 131 inFigure 17. The studs extend outwardly through slots 132 in the type-barsegment and are provided with a spring 133 held in place by a collar 134fast to the studs, I

the spring actuating upon the segment through a washer 135, thus holdingthe anvil in contact with the supporting pad.

- The segment is automatically swung in a path determined by thecurvature of the slots 132 to positions corresponding to the position ofthe card, thereby compensating for the different thicknesses thereof,and, to this end, there is provided a lever 136 fulcrumed at 137 upon afixed bracket 138, one end of the lever being provided with a fork 139designed to engage a pin 140 fast to the anvil 128. At the other end,the lever 136 is provided with a pin 141 through Y which the lever 136is rocked to change the position of the anvil. Said pin 141 is operatedby a link 142 which is in turn operati-vely connected to the shaft 94through an arm 143 fast thereto and a. pin 144 fast to the arm andengaging the lower end of the link 142.

Sometimes it is desirable to use cards having a comparatively thinpaper-frame. such as is illustrated. in Figure 21. In such cases, asuitable card-holding frame may be substituted and the compensatingmechanism be not used because the difference in thickness between thepaper-frame and the trated in Figures 22, 23 and 24, novel means areshown for switching and locking the ribbon mechanism. Instead of theswitching and locking means described at the beginning of thisspecification, the mechanism comprises a Geneva lock, that is to say, aplate 145 having a notch 146 engaging with a tooth 147 on thecard-holding frame. Upon moving the card-holding frame the tooth 147will be caused to engage with the notch 146, thereby swinging a shaft148, upon which the plate 145 is secured, from a position shown inFigure 22 to that shown in Figure 23. Said plate 145 is provided withtwo flat portions 149 against which the side of the card-holding frameslides, thereby preventing the shaft from swinging to its originalposition unless it is urged by the tooth 147. In order to relieve theplate 145 of the weight of the ribbonmechanismwhich may tend, undercertain conditions, to bind and to interfere with the free operation ofthe card-holdingframe, there may be provided an arm-androllerarrangement 150 engaging with a tooth 151 in a plate 58* which is fixedrelatively to the carriage. The shaft 148 is rotatably mounted on theplates 98 and moves therewith, being positioned thereon by means of anut 152 and a washer 153. The plate.145 is fast to the shaft 148 inorder to have it, at all times, in engagement with the tooth 147, butthe plate 145, being operatively connected to the ribbon-mechanism whichis stationary, must also be stationary. To this end, the shaft 148 isprovided with a longitudinal groove 154 engaging with a pin 155 driveninto a collar 156 which forms. an integral part of the plate 58. Theplate 58 is held stationary between a head 157 of the collar 156 at oneside of the ears 158 and a hub 159 forming an integral art of saidplate. In this manher, .when t e carriage is moved to letterspace thecard, the shaft and the plate are moved therewith, the rotatingconnection being maintained between the shaft and the stationary piece58 by means of the pin 155 engaging with the groove 154 in the shaft-148. I

According to another form of this invention, the'card-positioning meansare modified to provide a more positive adjustment therefor. Referringto Figures 26, 27 and 28,

in which this modification is illustrated, it

will be noted that there is provided a stop device 160 for limiting thelowermost posi tion of the card-holding frame and a separate stop device161 for positioning the card for the first line of typing upon thestencilmounted at one side of the plate 98, and is provided with a benttab 167 protruding through a hole 168 in the plate 98. When the handle19 is moved rearwardly, as shown in Figure 27, to drive the sector 20 bymeans of an extension 169, a spring 170, which normally holds theextension 169 awa from the sector, is stretched as shown in igure 86,thereby forcing the pawl 99 out of engagement with the tab 167, topermitline feeding of the plate after being sitluned tor the first lineof typing upon t e stencllsheet. In order to facilitate the adjustmentof the eccentric studs 164, each is provided with a nick 171 forreceiving a wrench, to rotate the stud and then to permanently lo cateit by either driving a pin m the plate 98 or by upsetting some metalinto the inch by means of a chisel. v

The modification hereinbefore described is illustrated in connectionwith means for adjusting the position of the platen relative- 1y to therinting point. To this end, there are providbd a plurality of brackets172 fast to the carriage 173 and screws 174 for approximatelypositioning the plates 98 upon said brackets. The screws are slightlytight ened and the frames are ta ped to position, whereupon screws 175hol 'ng the brackets to the carriage are loosened and the plates 98 aredoweled to the brackets at 176. It will be understood that the holes 177throu h which the screws 174 are passed, are consiferably larger thanthe body part thereof, thus permitting the adjustment of the platespreparatory to their being doweled t0 the brackets. It will beunderstood that in another form of this invention the adjustable featurehereinbefore described is eliminated, and, then, the side plates-98 aredirectly fastened to the carriage by means of screws 182 through holes183 in bent portions 184 of the plates 98.

As it is desirable to use a standard Underwood typewritin machine, andto rebuild as little as possib e for embodyin the stencil device in themachine, the she protrudes through the frame of the machine to theoutside thereof, and, in order to provide a bearing for the shaft at apoint where the frame is cut away to clear the carriage of the machine,there is provided a plate 17 8 fast to the frame'by means of screws 179.For the same reason specified, there is provided the bracket 138 fast tothe frame by means of screws 181,. said bracketbein rovided for thepurpose of car in the t d 137 upon which the lever 1 3 i% rockablymounted.

Sometimes, comparatively thin cards are used, and then, owing to thesmall difl'erence in thickness between the card and the stenciLsheet,the mechanism hereinbefore described may be omitted, the typebars beingneaaear flexible enough to take care of'the difierence in the thicknessand still deliver a clear impression of the types.

Variations may be resorted to within the scope of the invention, andportions of the im rovements may be used without others.
